从地理数据生成叠加地图图像(Generate overlay map image from geo data)

我需要生成一个透明图像，以便在地图上应用，类似于： Image_1或Image_2

我需要从数据集生成此图像：我有许多数据点（使用lat和long），我会生成此图像（服务器端）以在我的数据的地图上显示密度。

了解一些事情（图书馆或解决问题的最佳方法）吗？

I need to generate a transparent image to apply on map similar to these: Image_1or Image_2

I need to generate this image from a dataset: I have many data points (with lat and long) and I would to generate this image (server side) to show density on map of my data.

Know you something (libraries, or best way to solve my problem) about it?

那些是热图 。 Google地图已具备此功能，因此您应查看其示例和文档 。 它可以像在数据点中加载一样基本并将它们作为图层应用，也可以进行更多自定义。

Those are heatmaps. Google Maps already has this capbility, so you should check out their sample and the documentation. It can be as basic as loading in your data points and applying them as a layer or you can do much more customization.
